Quantum dots help shine light on room-temperature spintronics

A novel opto-spintronic nanostructure made from layers of quantum dots can transfer information between electron spin and light at room temperature.

Novel water-splitting material gives pores for thought

By covering cubic silicon carbide in nanopores, researchers have created an efficient light-powered material for splitting water to produce hydrogen.

Perovskite solar cells take a dip into large-scale production

A new, inexpensive dipping process using a sulfolane additive can produce high-quality perovskite crystalline thin film for use in solar cells.

Material offers new window – and mirror – on optical switching

Researchers have found a material that can switch between a window and a mirror in a quadrillionth of a second when struck by a short laser pulse.

New study reveals latest twists and turns of halide perovskites

Researchers have discovered that the electronic properties of halide perovskites hinge on the way their atomic lattice twists and turns.

Novel photonic material can turn towards the light

By combining photonic crystals with a polymer substrate, researchers have developed a photonic material that can move and fold when illuminated.

Clear benefits of novel electrochromic display
